kA

open class kA : SystemController

Acceleration feedforward gain. Used to induce acceleration based on changes over time to the setpoint.

Differs from a conventional kA gain applied to a target acceleration, rather, attempts to apply a gain to the rate of change of the setpoint.

Constructors

constructor(kA: Double)

Create a new kA gain.

Inherited properties

A null controller that does nothing.

Functions

open fun calculate(ignored: Double, setpoint: Double): Double

Calculate the next output of this control algorithm.

getCoefficients

open fun getCoefficients(): Array<Double>

Gets the current coefficients for this controller.

open fun reset()

Reset this controller back to an un-accumulated state, if applicable.

setCoefficients

open fun setCoefficients(@NonNull coeffs: Array<Double>)

Sets the coefficients for this controller.

Inherited functions

open fun compose(@NonNull plus: SystemController): CompositeController

Composes this controller with another controller, returning a new controller that is the composition of the two by summing the outputs of each controller together.

open fun compose(@NonNull other: SystemController, @NonNull combiner: DoubleBinaryOperator): CompositeController

Composes this controller with another controller, returning a new controller that is the composition of the two.

open fun pidf(): Optional<PIDFController>

Get the PIDF controller associated with this controller, if applicable.

setCoefficients

open fun setCoefficients(@NonNull coeffs: Array<Double>)

Sets the coefficients for this controller.
